EV Calculator: Best Boxes to Crack
MTG Booster Box EV Calculator
About EV Rankings
EV calculated from TCGPlayer completed sales data across 500+ sets, updated daily at 9 AM UTC. Each box's expected value factors in probability-weighted pull rates from MTGJSON booster sheet data, sellable bulk pricing, and current market conditions.
Box EV rankings compare every sealed MTG product by expected value. Total EV is calculated from the combined market value of all singles inside the box, then divided by the box price to produce the EV ratio; the higher the ratio, the better the return if you crack it.
Filter by box type to compare play, draft, set, or collector boosters head-to-head. For per-pack analysis and risk metrics, check the pack EV rankings. Browse all sealed products on the boxes page. Run a historical backtest to see how box EV has changed over time, or use the box opening simulator to model expected outcomes before you buy.
All EV calculations use TCGPlayer market prices reflecting real transaction data. Rankings are recomputed daily as card prices shift. Past EV performance does not guarantee future results; prices change as cards rotate, get reprinted, or see metagame shifts.

Frequently Asked Questions
What is booster box expected value?
Expected value (EV) is the total market value of all singles you can expect to pull from a sealed box. SpellBook Finance calculates EV from current TCGPlayer market prices across every possible card in the product.
How is EV ratio calculated?
EV ratio divides the total expected value of the singles inside by the box's market price. A ratio above 1.0x means the cards inside are worth more than the box costs, making it potentially profitable to open.
Which MTG boxes have the best EV?
Collector booster boxes and premium sets tend to have the highest EV ratios. Check this page daily — rankings shift as card prices move. Filter by box type to compare play, draft, set, and collector boosters head-to-head.
